The papyrus was written in about 1500 BC, but it is believed to have been copied from earlier texts. The Ebers Papyrus is a 110-page scroll, which is about 20 meters long. Along with the Kahun Gynaecological Papyrus (c. 1800 BC), the Edwin Smith papyrus (c. 1600 BC), the Hearst papyrus (c. 1600 BC), the Brugsch Papyrus (c. 1300 BC), the London Medical Papyrus (c. 1300 BC), the Ebers Papyrus is among the oldest preserved medical documents. The Brugsch and the London Medical papyri share some of the same information as the Events Papyrus. Another document, the Carlsberg Papyrus, is identical to the Ebers Papyrus, though the provenance of the former is unknown.
